Great job on the website cinyc!
I was looking at the population change map for Norfolk, Va. I saw what I thought must have been a mistake for Census tract 38, a 87% decrease in a nice area that's been pretty stable. Looked around a bit and found this:
https://data.census.gov/cedsci/table?q=virginia%20population&hidePreview=true&table=P1&tid=DECENNIALSF12010.P1&g=0400000US51_1400000US51710003800&vintage=2018&layer=censustract&cid=DP05_0001E&lastDisplayedRow=15has a note with the revised count and mentions the 2010 Census Count Question Resolution - which is where cities and towns can question what the count was, and the census makes a revision. I don't know if there is data anywhere that incorporates all the revised counts from this.
